Personal Profile

Qi Wang is currently an Associate Professor at the School of Mathematical Sciences, Dalian University of Technology. He received his bachelor's degree from Shandong University of Aeronautics in June 2015, and his master's degree from the School of Mathematics, Shanghai University of Finance and Economics in January 2018. He obtained his Ph.D. in March 2022 from the Graduate School of Information Science and Technology, Osaka University, under the supervision of Professor Susumu Ariki.

From June 2022 to August 2025, he held a postdoctoral position at the Yau Mathematical Sciences Center, Tsinghua University, where he was selected for the "Shuimu Scholar" Program and worked under the supervision of Professor Yu Qiu. His research has been supported by several funding programs, including the National Natural Science Foundation of China (Youth Science Fund Program, Category C), the China Postdoctoral International Exchange Program, the China Postdoctoral Science Foundation (General Program), and the JSPS Research Fellowship for Young Scientists.

Research Interests

Qi Wang's research lies in the representation theory of algebras, with a current focus on two main directions. On the one hand, he studies the representation theory of classical algebraic structures arising from Lie theory and knot theory, such as Hecke algebras, $q$-Schur algebras, and Temperley–Lieb algebras. On the other hand, he investigates the roles of $\tau$-tilting theory, silting theory, and cluster theory in the representation theory of these algebras. Typical problems include the $\tau$-tilting finiteness of $q$-Schur algebras and the symmetry properties of their silting quivers. Some representative results are listed as follows:
